Also they toss in the "conclusion" that carbon posts are good for lighter weight, but I've seen no evidence for that, especially since I'm fairly sure the lightest post in their test is the Thomson (which is what I use).

The issue is you need the post to be strong enough to handle compressive force from the clamp and that requires a lot of material.

The lightest posts out there are carbon (AX-Lightness, for example), but that's the boutique bleeding edge.

The lightest setback post is the Ritchey Carbon, at 170 grams.

Thanks for posting the test! (minor editing to NGMN's quote)But I disagree with you DJ - you don't have to go boutique-expensive or "bleeding edge" to go light. An OMNI seatpost, zero setback, is 116g, uncut.Performance Bike Shops had a house brand "FORTE" "Precision Seatpost" which, even with setback, came in at 145g uncut, untuned. Still lighter than the Ritchey Carbon, all for $45US. Donald (currently with the lightest bike here) used the Forte Precision seatpost and with some minor tuning brought it down to 86g (ish?)... so... boutique? Hardly.

Well, Donald's parts are literally bleeding edge: if he removed another 5 grams from that post he'd end up on the edge of the road, bleeding . He'd better watch what he eats because if he gains any weight he's going to push his bike over the limit... (I'm a Donald fan: his bike is amazing. I'm just teasing.)

I'm talking about commercially available parts. That said, I didn't realize the Forte (or whatever is behind it) came in that light.

DJ, haven't seen the forte post, but I do have one that's straight 27.2 / 350mm. Comes in at ~165g uncut, untuned. Just changing the twin adjustor bolts to titanium ones will bring it down ~8-10g I believe.

Is this an all American post test?Just asking because I can not see brands from other than US based manufacturers.Correct me if I am wrong.I partly agree with prendrefeu because the Omni seat post is identical to the Token carbon post.So where are 3T,Deda,ITM,KCNC,Token,Merek and many others?Aren't above mentioned posts commercial available in the US?WW know where to get light,reliable and not overpriced seat posts.Not so VeloNews.

It's obviously taken from the Schmolke site so you can guess who the winner is, but the data is still pretty interesting and shows how widely varied the flex is between the posts. It should form an interesting point of comparison to the VeloNews test. I also like that the test displays the data in industry standard Nmm instead of fractions of inches.So the comfiest (Schmolke) 31.6 post has a deflection of 71Nmm whereas the stiffest (FSA) 31.6 is at 273Nmm. Both these are carbon btwy. You can also conclude that there is basically no significant relationship between comfort and price or for that matter comfort and weight.

Don't completely understand the fine details of the description but I would discount the test methodology there.

Maximum deflection at low loads does not automatically equate to a good quality ride. The ability to attenuate for multitude of road buzz frequencies is far more crucial in real world riding. Its almost like saying the suspension fork with the softest spring settings is the best fork for MTBs !

The Velonews methodology is far more realistic though as I mentioned in a previous comment, its only really useful if they tested the posts at a variety of undulation heights and wheel spin speeds. And that the human subject is taken out of the context.
